SEAT-SPRING FOR VEHICLES.

SPECIFICATION-forming part of Letters Patent No. 275,555,'dated April 10, 1883,

Application filed September 13, 1882. (No model.)

1o jects of my invention are to secure the sustaining strength of the metal placed. on its edge and make available more completely the elasticity of the steel used in the spring. I attain these objects by devices illustrated in the accompanying drawings, in which- Figure 1 isa perspective view with one end of the seat-board broken away; Fig. 2, a section across the spring along the line 00 w.

A is the body or box of the wagon; B, the seat-board; O,the clip to hold the spring obliqnely under the seat-board; E, the spring, with arms 0 at right angles with it; F G, the clip or standard in which the ends of the springs are hinged.

sections of which between B and the arms 0- are brought to a vertical position and then to an outward inclination, while the middle portion is held at its original angle. The torsion of E in this variation of the inclination of differents parts between its arms produces the spring in the seat. The spring is deflected inward when set on the board, so that when the plane of the spring is vertical its outward deflection will equal that originally inward. When, on further depression, the plane above the springboard inclines outward the deflection will again be inward.

What I claim is The fiat bar spring with arms held in standards (the line of its cross-section inclining inward about twenty-two degrees) and clasped in the middle by a clip, to which it is bolted and by which it is held firmly to the seatboard, substantially as described.
